The ilrairinggi,l illustrate a satisfactory reduttion of'thel improvement to practice` Figure l is a top plan view of u portion `nf an automobile illustratinpr the application of the' improvement.

Figure. :3 is a side elevation thereof. the dot and dash lines showing the relation of the wheel of the vehicle and the ground with the bumper.

Figure 21 is a sei-tional view. on an enlarged .scale and is approximatehv on the The brackets whieh provide the spring housings ol' |n ilnproreiuent muy lie ruriously shaped in rrosx seetion. one of such -lu1|e|\'et: in Figure l of the drawings, huringg its: inner fare straight. and the other havin;r its inner fare of an angle formation. 'l`he lirarkets are bolted or otherwise Serured to the side liars: of the automobile frame. and the bumpers may. of rouise, he arranged at. hoth the front and rear of the vehicle.

l'lfcepl for the eross `sertional formation. mieli of the lnarkets l is provided with a. longitudinal barrel 2 which forms a housilugr for u hclionl spring! 3. fThe harrel portion of each of the brackets has its onter end provided with an opening of a size approximatelii equallinpY that of its bore. und its provided with n restricted opening. These openings receive therethrough r, |921. serial No. 513,395.

a rod 4. (lne end of the rod is reduced, as at 5 to be rereired through the smaller inner openings in the brackets. the said reduced end beio; Y threaded and beingr engaged by adjusting.: nuts i. The springr 3 exerts a pressure between the inner wall of the barrel and ihe houlder lwtwcen the rod and the reduced extension thereof, thc said spring bein; disposed around the reduced extension .fof the said rod` and the tension of the spring may be regulated hy adjusting the nuts ti. e i

laehlof the rods l has its outer end en larger! to provide the saine with a head 7, the said head bein; r eentrally formed with an extension in the nature of a tongue or knuckle S.

The bumper har 9 may be of any construction and has secured upon its inner face, adjacent. to its ends plates l0 rorided with spaced ;\xte.nrlin;, Y ears ll. Trliese ears are arranged to reeeire therebetween knuckles 7 of the respective rods 4. a pivot l2 passin r through thi.l ears and knuckles.

From the above description. when taken in connection with the drawings, it will be seen that the bumper har 9 is pirotally con. neeted to the rod 4 and that the rod 4 is influenced by the spring 3. The. springs 3 will reduce the. im act of force should -the bumper har be iroilght against au obstacle. and the hinge. connection between the bumper har and the rods will permit of the said bur assuming an angle and lthus present an angle surface to the object contacted. The result is that instead of a. straight cotact with theohstarle. the bumper willihnve n wiping action thereugainst. the springs absorbingthe shock incident to the Contact before injnr)` ran he inflicted to either the vehicle or the object contacted therewith, and the :ingle arrangement of the bumper' will eause the vehicle to swerve away from the object contacted. u

It is thought that the foregoing' descri L tion. when taken in connection with t e drawings will fully set forth the construetion, operation and iulvantages of the improrement and that further detailed descri tion will not he necessary. lt is thouglit necessary to state. however` that the 1mprovement is not to be restricted to theprecise details of construction herein recited and that I um entitled to all such ehnnf'es therefrom as fall within the scope of w at is claimed.
